Operation Instructions on Keys Switching Modes

DTD is in operation mode (the first level) when the power is switched on. Press once to switch to the regulation mode (the second

level), or press for more than 3 seconds in operation mode to switch to the initial setting mode (the third level). Press once in other screens to return to the operation mode.

Switching Functions

Press in each mode to select functions. Press once to switch to the next function, or return to the first function when press

in the last function.

Modifying Settings

Select the item to be set up by using and . Next, press . If the item to be set up is a value, the last digit of the SV will

flash. If you press to select parameters, the SV will flash. Press to increase the value of the digit or select parameters. When

setting up the value, press to left shift to the digit to be modified.

Examples

1. DTD from STOP to RUN: Press once and select parameter . SV will display . Press and will flash.

Press to save the setting and will stop flashing.

2. Modifying SV from 80 to 120: Press and display 0080 (the last digit in right hand side 0 will flash). Press once and 8 will

flash. Next, press 4 times and “2” in the display 0020 will flash. Press once and the 100s digit 0 will flash. Press

once and ”1” in the display 0120 will flash. Press to complete and save the setting.

Input Settings Setting up Input Type

When DTD is switched on, SV will display the type of the input sensor (default K1 = thermocouple type). Press for more than 3

seconds in the operation mode and PV will display the parameter . Press to select the sensor types (see the table below) an

press

to complete and save the setting. The screen will return to the screen of operation mode.

If the setting is current input, a 249Ω resistor has to be connected to the current input terminals.

Setting up Input Unit

In the operation mode, press for more than 3 seconds and PV will display the parameter . Press once to select the

unit. If the input type is thermocouple or platinum resistance, the PV will display . In this case, press to select the temperature unit (°C or °F). If the input type is an analog input, the PV will display . In this case, you can set up the position of the decimal point

for the analog input. Press to complete and save the setting.

Setting up Input Range

After you complete setting up the input unit, press once to display the parameter . Use and to set the maximum

value for the temperature range. Press again to display the parameter , and use and to set the minimum value for the temperature range. The default range is the maximum range measurable (see the table below) and both parameters cannot exceed this range. When PV exceeds the range, PV will flash and DTD will stop its operation.

When in analog input, the temperature range also refers to the maximum and minimum input values. For example, when 4 ~20mA input is adopted, = 2,000, = 400. That is to say, PV = 1,200 refers to the input is 12mA and the unit is 0.01mA.

Adjusting Input Inaccuracy

When there is the need to correct the measured input PV, press once in the operation mode to enter the regulation mode. Press

repeatedly until the parameter of input compensation value appears. Modifying this parameter will make the PV = measured

value + input compensation value. Press again to display the parameter of input gain and make PV = measured value × (1 +

input gain/1,000) + input compensation value. Press again and display the parameter of software filter (default = 2). Increase this parameter to enhance the stability of the PV; however, this will result in slow reaction to the input value.

Control Settings Setting up Control Mode

In the operation mode, press for more than 3 seconds and PV will display the parameter . Press for 4 times to display

the parameter . The default setting of this parameter is “On/Off control” . Use to select PID control , PID

programmable control or manual control . Press again and display the parameter for selecting the control

method. You can select heading (default) or cooling . Press to return to the operation mode.

Setting up RUN and STOP

In the operation mode, press and display parameter . The default is RUN . Use to select STOP . Press

to complete the setting and the output will be disabled.

Setting up On/Off Control Parameters

Press in the operation mode. If DTD is in On/Off heating mode, the PV will display ; if in On/Off cooling mode, the PV will display . Modify these parameters to set up the hysteresis of On/Off. The default setting is 0 (without hysteresis). When the output reaches SV, the control output will be disabled. When the input is bigger (cooling) or smaller (heating) than the SV and hysteresis, the control output will be enabled. When the On/Off hysteresis is not 0, the control output will be like the diagrams below.

Setting up PID Parameters

When in PID control mode, you have to first decide the On/Off cycle time for the control output, i.e. the control cycle. Press in the

operation mode and PV will display . Press 5 times to display the parameters of heating control cycle or cooling control cycle . Set up the cycle depending on the reaction speed of the control system. In principle, the faster the reaction, the shorter the cycle and more accurate the control. A short control cycle indicates that there will be more times of On/Off. If you adopt relay output, the short cycle will shorten the life span of the relay. Therefore, it is recommended that you adopt voltage output in the PID control mode. The default setting of the control cycle is 20 seconds.

Parameters P, I and D can be set up manually or auto-tuned by DTD. Follow the steps below for the auto-tuning.

Press in the operation mode and PV will display the parameter . In RUN state , set the parameter to and DTD will perform an auto-tuning. The AT indicator will flash and after the setup is completed, the AT indicator will be off. The PID parameters will be written in automatically and saved. To set up the parameters manually, enter the regulation mode and select the parameter .

Press once to display the parameter of proportion band , indicating the range where P control is enabled. See the diagrams in the next page.

The bigger the parameter P, the less possible that the heating will exceed the SV and the longer it will take for the temperature to reach SV. This is suitable for the control system with faster reaction speed. On the contrary, the smaller the parameter P, the more possible that the heating will exceed the SV and the shorter it will take for the temperature to reach SV; however, unstable control is more likely to occur. Smaller P is suitable for the control system with slower reaction speed.

How to set up the parameter of integration time I : The bigger the value I, the longer the integration time, as well as the time to reach the SV. Unstable control is also less likely to occur. On the contrary, the smaller the value I, the shorter the integration time, as well as the time to reach the SV. Unstable control is thus more likely to occur.

How to set up the parameter of differentiation time D : The bigger the value D, the faster reaction speed and repression power DTD has for the external interference. However, if D is too big, the repression power that is also too big will result in out of control of the situation.

Parameters for PID control: The default integration output volume is to allow the temperature to fast reach the SV. The parameter is for compensating the steady error in PD control. The two parameters are the output percentages when the input reaches the SV.

Assume the output percentage is 20% when PV = SV, the best setting for this parameter is 20.0. The parameter can be a reference value when being auto-tuned. It can also be adjusted manually.

PID Programmable Control

PID programmable control offers 8 steps for you to plan for the temperature control program. You can set up your own number of steps and times of execution and directly monitor the current executing step, remaining time and the current SV. There is only 1 group of PID parameter settings and by the first step, you can directly control the temperature to the SV. You can also set up the control status that after the program ends, DTD will either stop the output or stay at the last SV.

Setting up the parameters in the program: To set up the parameters in the program, you have to first enter the initial setting mode and set the control mode as programmable control to further display the parameters which you can set up.

In the operation mode, press and enter the regulation mode. PV will display the parameter of the number of steps to be executed . Maximum 8 steps can be planned in this parameter.

After the setup is completed, press to display the parameters for setting up the execution loops . The range of this parameter is 1 ~ 99, e.g. 2 means executing twice.

Press to setup the parameter for the action of DTD after the program ends. Set this parameter as , indicating that the control output will stop after the program ends. Set this parameter as , indicating that DTD will stay at the last step before the program ends.

Press and display the parameter of SV of step 1 . Use and to set up the SV. Next, press to display the

parameter of the executing time of step 1 . Use and to set up the time (unit: minute; Max. 9,999 minutes). After the

setup of step 1 is completed, press to set up the parameters (SV and executing time) of the next step. Please note that the number of steps is decided by the setting of the parameter . The number of steps that exceeds the setting will not be displayed on the

screen of DTD during the operation. Press to return to the operation mode and press to display the parameter . Set this parameter as and execute the control. DTD does not offer pause function; all executions start from step 1.

In the operation mode, on the SV display, you can monitor the present value (default) , remaining executing time , or the

executed number of loops and steps . Use to switch between different monitoring modes and press to display the selected monitoring mode. When the execution of the program ends, the remaining executing time will be displayed as “0” and the executed loops and steps as .

Setting up Manual Control

Select manual control in the control mode and set up the control cycle first. Next, press repeatedly in the operation mode until

is displayed. Use and to modify the output percentage. During the execution , the output percentage will vary upon different output percentage settings. The output setting will be saved and the saved setting will be adopted next time when DTD is switched on. The default setting is 0%.
